D - Dogged by his own questionable play-calling and game-management decisions, Jason Garrett oversees an underachieving team plagued much of the season by penalties, turnovers and a low football IQ.

General manager

C - Jerry Jones deserves credit for bolstering the secondary, but the two guards he signed in free agency to shore up the offensive line are clunkers.

Overall

D - Yes, four of their five losses came against division leaders and another was at Seattle, where the Seahawks are undefeated.

Still, there's not much to like about a team that far too often repeated the same mistakes over and over en route to a disappointing 3-5 showing in the first half of the season.

And let's not forget, they easily could have lost to Tampa Bay and Carolina.

Run offense

D - It has been ranked near the bottom of the NFL all season and has been flat-out nonexistent the last three games without DeMarco Murray (foot). In his absence, the ground game has averaged a putrid 2.4 yards per carry.

Run defense

C - Solid most of the season, it collapsed badly in the second half against Atlanta because of terrible tackling and a failure to close on ball carriers in key situations (see Julio Jones juking DeMarcus Ware in the backfield on third-and-1 in the fourth quarter).

Pass offense

C - Much of the blame for Tony Romo's league-high 13 interceptions can be assigned to the sloppy route running of Dez Bryant and Kevin Ogletree. While Dallas is near the top of the league in passing offense, it's near the bottom in points per game with an 18.8 average.

Pass defense

C - The secondary is better with Brandon Carr and rookie Morris Claiborne at cornerback, but it has only two interceptions and got exposed by Falcons quarterback Matt Ryan and his receivers.
